I will have to dispute your rebuttal for the following reasons:
1) The ATP project does not need to account for differences in hop up design as the project was created using computer models that only dealt with the aerodynamics after the bb has left the barrel.
2) the graphs only show data up to ~220 ft because they only predicted the model to a maximum amount of bullet drop of 60 inches obviously if you have an increase in overhop, or simply aim above your target you can easily exceed 60 inches of compensation.
3) we know that the accuracy of an airsoft gun is dependent on a number of factors beyond what weight of bb is in the gun.
However, I still conclude that given a perfect gun (mathematical model) and amount of hopup set correctly, that 300 fps muzzle velocity (slightly faster for heavier weight ammo) will produce better results based on the relationship of "the derivative of the rotational velocity vs derivative of linear velocity" curve.
If you have evidence to suggest otherwise, please share. (it's kind of my thing)
